TRAINING
Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information. (Replace-
ment manuals and safety decals are available from
your dealer. To locate your nearest dealer, check
the Dealer Locator at www.WoodsEquipment.com,
or in the United States and Canada call 1-800-319-
6637.) Failure to follow instructions or safety rules
can result in serious injury or death.
If you do not understand any part of this manual
and need assistance, see your dealer.
Know your controls and how to stop engine and
attachment quickly in an emergency.
Operators must be instructed in and be capable
of the safe operation of the equipment, its attach-
ments, and all controls. Do not allow anyone to
operate this equipment without proper instruc-
tions.
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service person-
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan-
grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Never allow children or untrained persons to
operate equipment.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
Do not connect a low-pressure hydraulic hose
into a high-pressure system—it will burst the hose.
Do not use a high-pressure hose in place of a low-
pressure hose—it is possible to rupture the valve.
Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS systems in “locked up” position at all times.
A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without this
weight, tractor could tip over, causing personal
injury or death. The weight may be attained with a
loader, front wheel weights, ballast in tires or front
tractor weights. Weigh the tractor and equipment.
Do not estimate.
Make sure all safety decals are installed.
Replace if damaged. (See Safety Decals section for
location.)
Make sure circuit selector lever does not hit
tractor cab, etc. throughout operating range of 3-
point hitch of tractor. Bend lever, if necessary, to
clear cab, but it should still be convenient to oper-
ate from the tractor seat.
OPERATION
Do not allow bystanders in the area when oper-
ating, attaching, removing, assembling, or servic-
ing equipment.
Do not operate equipment while under the influ-
ence of alcohol or drugs.
Operate only in daylight or good artificial light.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all
moving parts.
Always comply with all state and local lighting
and marking requirements.
(Safety Rules continued on next page)
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, concern,
judgement, and proper training of personnel
involved in the operation, transport, maintenance
and storage of equipment.
It has been said “The best safety device is an
informed, careful operator.” We ask you to be that
kind of operator.

OWNER SERVICE
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service person-
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan-
grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Before working underneath, read manual
instructions, securely block up, and check stability.
Secure blocking prevents equipment from drop-
ping due to hydraulic leak down, hydraulic system
failure, or mechanical component failure.
Never perform service or maintenance with
engine running.
Before dismounting power unit or performing
any service or maintenance, follow these steps:
disengage power to equipment, lower the 3-point
hitch and all raised components to the ground,
operate valve levers to release any hydraulic pres-
sure, set parking brake, stop engine, remove key,
and unfasten seat belt.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head.
BLADE CUTTING EDGE
To reverse the cutting edge
1. Remove the 5/8" plow bolts.
2. Remove the cutting edge from the moldboard and
reinstall with the sharp edge down.
3. Replace cutting edge when both edges are worn.
LUBRICATION
Weekly
Oil the pivot pins with SAE 30 oil.
8 Hours
Grease optional skid shoes.
BOLTS
1. Check bolts periodically to be sure they are tight.
2. Replace bolts as needed.
NOTE: Replacement bolts must have the same
strength markings on the heads. Refer to bolt torque on
page 47.
CLEANING
After Each Use
● Remove large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
● Inspect machine and replace worn or damaged
parts.
● Replace any safety decals that are missing or not
readable.
Periodically or Before Extended Storage
● Clean large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
● Remove the remainder using a low-pressure water
spray.
1. Be careful when spraying near scratched or torn
safety decals or near edges of decals as water
spray can peel decal off surface.
2. Be careful when spraying near chipped or
scratched paint as water spray can lift paint.
3. If a pressure washer is used, follow the advice
of the pressure washer manufacturer.
● Inspect machine and replace worn or damaged
parts.
● Sand down scratches and the edges of areas of
missing paint and coat with Woods spray paint of
matching color (purchase from your Woods
dealer).
● Replace any safety decals that are missing or not
readable (supplied free by your Woods dealer).
See Safety Decals section for location drawing.
